Description

 Foliar fertilizer composition containing sodium alginate oligosaccharide and application thereof

 The present invention relates to physiological metabolism of plants, and more particularly to the use of amino acids, sodium alginate oligosaccharides and trace elements as main active substances in plant growth promotion. Background technique

 Traditional chemical fertilizers have a single fertilizer effect and serious pollution. The long-term use destroys the soil structure, while the artificial plant growth regulators are likely to cause table pollution, resulting in a decline in the quality of agricultural products. After China's accession to the WTO, food safety has become a key factor affecting the competitiveness of agriculture and food industry in the international market. The development and application of safe production technology for pollution-free agricultural products is extremely urgent. The natural extracts of amino acids and marine oligosaccharides can make up for the deficiency of traditional fertilizers and synthetic plant growth regulators in China. As a new type of foliar fertilizer development, it can help improve the safety of agricultural products in China and protect the environment.

 Some oligosaccharides such as chitooligosaccharides have been used in the field of plants since the 1970s, and have functions such as inducing plant resistance and promoting plant growth.
